Description

mold with insert

technical field

The utility model relates to a mold for producing bottle barrels, in particular to a mold for producing bottle barrels with an in-mold blowing process.

Background technique

Existing buckets for bottled water, hereinafter referred to as buckets, are produced by an in-mold blowing process. The general production process is as follows: extrude the molten material tube from the outlet, the material tube grows from top to bottom, and then the left mold and the right mold are closed. After the left and right molds are closed, the inside is a predetermined shape. The inner cavity, the left mold and the right mold clamp the material tube in the middle, and then the blowing needle in the center of the outlet blows air into the material tube, so that the material tube expands and finally fits the inner cavity of the mold. The left and right molds are For the mold with liquid cooling channel, the material tube will be cooled and set after fitting the left mold and the right mold. Thereafter, the left mold and the right mold are separated, and the bucket semi-finished product can be taken off.

For some bucket products, the difference is only in the graphics and/or text trademark content on a certain surface. At this time, it is reflected in the structure of the mold that there is a replaceable insert on the left mold and/or the right mold, the graphics and The content of/or word mark is exactly molded by this insert, when producing the bucket with different trademark content, just load onto corresponding insert on left mold and/or right mold.

Taking the left mold as an example, as shown in Figure 1, the existing assembly structure between the insert and the left mold is: on the left mold, a flat-bottomed inlay pit is milled out from the working surface of the mold with a milling cutter, and the inlay Screw holes are provided at the bottom of the hole; inserts are put into the inlay pit, and screws are passed through the screw holes to tighten to the screw holes on the insert, and the assembly of the insert and the left mold is completed. Since such an assembly structure needs to be milled with a milling cutter inserted into the working surface of the concave left mold, the general-purpose milling machine can only be milled with a long milling cutter, but the rigidity of a long milling cutter is inferior to that of a short milling cutter. , so the control of dimensional accuracy is not as accurate as when short milling cutters are used. If a machining center is used for milling, the processing cost is relatively expensive.

Therefore, it is necessary to improve the structures of the existing inserts and molds.

Contents of the invention

The utility model provides a mold with inserts, aiming at reducing the cost of the assembly structure of the inserts on the mold.

Adopt the following technical solutions:

A mold with inserts, including a left mold; in particular, the left mold is at least composed of a left main mold assembled together and several left sub-moulds; at least one left sub-mould is formed on the left main mold The semi-cylindrical surface is called the left mold arrangement surface; the left sub-mould is provided with a matching surface that can fit the left mold arrangement surface; the left sub-mould is arranged and fixed on the left mold arrangement surface; at least one left mold An inlaid hole is formed on the sub-mould; an inlaid block is also provided in the inlaid hole; at least two positioning grooves are formed on the periphery of the orifice of the inlaid hole on the side of the matching surface; the A positioning piece is provided on the side of the insert; when the insert is inserted into the mounting hole, the positioning piece falls into the positioning groove.

The structural principle of the utility model is as follows: through the structure that the main mold and the sub-mould can be separated from each other, a modular mold is realized, which has many advantages compared with the existing integral mold. At this time, bottle barrel manufacturers only need to configure a small number of main molds, and configure corresponding sub-moulds for bottle barrels with different shapes. Since the cost of sub-moulds is lower, this can greatly save the purchase cost of molds. In addition, the assembly structure of the insert and the sub-mold effectively reduces the processing difficulty and cost, which is reflected in that the inlay hole on the sub-mold can be processed on a general-purpose wire cutting machine, and the positioning groove can be made on a general-purpose milling machine. be made of. As for the insert, it can still be processed by using a general-purpose wire cutting machine.

For the assembly of the insert and the positioning piece, threaded connection or hole pin assembly can be used. The hole pin assembly refers to making a hole on the insert, the positioning part is a pin, and the pin is inserted into the hole; the hole for the hole pin assembly can be a blind hole or a through hole; the hole for the hole pin assembly Can be an overfit, clearance fit or interference fit with the pin.

A mold with inserts, including a right mold; in particular, the right mold is at least composed of a right main mold and several right sub-moulds assembled together; at least one right sub-mould is formed on the right main mold The semi-cylindrical surface is called the arrangement surface of the right die; the right sub-mold is provided with a matching surface that can fit the arrangement surface of the right die; the right sub-mold is arranged and fixed on the arrangement surface of the right die; at least one right die An inlaid hole is formed on the sub-mould; an inlaid block is also provided in the inlaid hole; at least two positioning grooves are formed on the periphery of the orifice of the inlaid hole on the side of the matching surface; the A positioning piece is provided on the side of the insert; when the insert is inserted into the mounting hole, the positioning piece falls into the positioning groove.

For the right mold with the above structure, the assembly scheme of the insert and the positioning piece can refer to the content described above about the left mold. That is: for the assembly of the insert and the positioning piece, threaded connection or hole pin assembly can be used. The hole pin assembly refers to making a hole on the insert, the positioning part is a pin, and the pin is inserted into the hole; the hole for the hole pin assembly can be a blind hole or a through hole; the hole for the hole pin assembly Can be an overfit, clearance fit or interference fit with the pin.

The mold with inserts of the utility model has the following advantages: the mold investment cost of the production enterprise can be greatly reduced, the auxiliary time for mold repair and mold replacement is obviously shortened, and the assembly structure of the insert and the sub-mould makes the processing difficulty and cost of the mold effective reduction.
